Combined with the latest graphene heavy-duty anticorrosive coating technology and metal materials introduced by China Crystal New Materials Holdings Co., Ltd., China’s first recyclable graphene diamond calciner. Its calcination time is 1/3 less than that of a traditional refractory brick calciner, which will greatly improve the quality and efficiency of synthetic mica flakes.
At present, the traditional refractory brick calcining furnace generally adopted in the world has high iron content, many impurities, and it is difficult to guarantee the quality. The post-processing cost of the calcined synthetic mica sheet is also high. In particular, the use of refractory bricks in the past was time-consuming and labor-intensive, and it is difficult to treat broken refractory bricks as solid waste, which does not comply with current environmental protection policies in China and severely restricts the development of the synthetic mica industry.
The graphene diamond calciner took 4 years to develop and has overcome a series of core problems from basic materials to design to process technology. The relevant experts of its research and development team revealed that the biggest highlight of the new graphene diamond calciner is that the calcination time is one-third less than that of the traditional refractory brick calciner, which can be released in 55 hours. Yuan, and the raw material utilization rate reaches 95%, which greatly improves the quality of synthetic mica tablets. From the experimental point of view of the current high-tech calcining furnace, the synthetic mica flakes produced are free of impurities, thin, and soft, which can greatly reduce the cost of post-processing.
